The title compound, [Zn2Cl4(C12H14N4)2]·2C3H7NO, is located on a centre of inversion with one half of a complex molecule and one dimethylformamide solvent molecule in the asymmetric unit. The ZnII ion is tetrahedrally coordinated by two organic ligands and two chloride ions. Each organic ligand acts as a bidentate ligand, connecting two ZnII ions, resulting in a dimeric [2:2] metallamacrocyclic structure. Adjacent molecules are further linked by N-HCl hydrogen bonds and the solvent is linked to the complex by N-HO hydrogen bonds.
